RU LING-PEN.

SPECIFICATION forming part' of Iletters Patent No. 531,124, datedDecember 18,1894.

Application filed August-16,1894. Serial No. 520,482. (No model.)

Be it known that I, LEWIS J OHNS'ON',l a citizen of the United States,residing at Willmar, in the ,county of Kandiyohi and State of Minnesota,have invented certain new'and .useful Improvements in Ruling-Pens, of

Which the following is avspeciiicationyreference being had therein tothe accompanying drawings. Y

My invention relates to ruling-pens and is designed with especia-lreference for use by accountants in ruling ledgers, trial and otherbalance sheets and for any purpose of drawing 'lines-to which this classof-'instrumen ts is` generally applied.

One purpose of 'the invention is the provision of a pen having rotarysingle and double line markers ;`also, in 'having the saidv markersrelatively adjustable to vary the. space between the lines tosuit thefigures and' the required stylefof ruling.

A still further object of the invention is a guard s o disposed withreference to one of the markers that when the pen is held in oneposition both markers will'touch and rule the paper but on reversing theposition of the pen only one marker will touch and line the paper. j Theimprovement will be more fully set forth hereinafter and claimed and isshown in the accompanying drawings, inwhich-k Figure l is a frontelevation of the preferred form of pen showing the two-rotary markers.Fig. 2 is a section on theline 2 2 of Fig. 1 looking to the right. Fig.3 is a sec' tional detail of the two markers on a larger scale. 1 Thepen comprises a hollow handle A which constitutesl the fountain, and asingle and double line rotary marker B and C, respectively, journaled inthe cheeks of the head D. A shaft E is journaled at its ends in thecheeks d and the. rotary markers B and C are mounted thereon andrelatively adjustable to and from each other to vary the distancebetween the lines, A binding screw 2 passes through a hub portion of themarker C and secures it in the'desired position. On loosening thebinding screw 2 the marker() can be moved to and from the marker B sothat theruled lines may be asv close together or as lhandle can bereplenishedv and the bore orv ,passage 3' in the head cleaned. A valvevE Ifcontrols thepassage 3 to shut off or` regulate the 110W of the inkto the markers. A packing is provided -at the outer or delivery end ofthe passage between the, cheeks d to distrib- 4Ente the ink'and supplythe same in proper quantity to-the markers;Y A binder 4 secures thepacking in place.' This packing is of any absorbent material suitablefor the provision iof an ink distributing padand may be felt',

,fchamois or any' fabric.

The guard G is provided by ,extending the edge of one ofthe cheeksbeyond the periphery of themarker a sufficient distance to one markerwill rule.

On'reversing` thepo-v sitio'n or slant ofV the pen both markerswill bebrought into operative position.

The operation of the pen is as follows: The

fountain being supplied lwith. ink andthe valve opened the pad VF willbecome mois-A tened. Onfus'ing the pen in the ordinary manner themarkers will be inked by contact withl the pad and deposit the same onthe paper inthe path of the markers. A suitable capY will be provided toprotect the markers and pad and prevent the drying of the ink and thelodgment of dust, &c., on the markers.

' .It will be observed that the rotary markers D and C are mountedY uponthe same shaft E and are of like diameter so that the marking` edgeswill be in a plane parallel with the said shaft. The marker B isprovided on its inner sidev with a hub portion b and the marker C isprovided on the opposing side with a tubular extension J to receive thehub portion d of the marker B which latter is adapted to telescopetherewith in the adjustment of the markers Bl and C to and from oneanother to vary the distance apart of the ruled lines. By thisarrangement the two markers in effect may be considered as one in whichthe ruling edges are adapted to be separated a greater or less distanceas required.

The guard G, as shown most clearly in Fig. 2, is located wholly to oneside of a plane passing vertically through the axis or shaft in thedirection of its length about which the markers C and B rotate. Hence,when the pen is slanted toward the side of the plane farthest from theguard both markers will come in contact with the paper and rule thesame. On slanling the pen to the side of the plane nearest the guard thelatter will come in contact with the paper and lift the marker Ccoutiguous thereto from engagement with the paper and as a result onlyone line will be ruled. This operation is readily understood when it isremembered that the edge of the guard projects a short distance beyondthe active edge of the contiguous marker.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-` l. In a ruling pen, the combination of asupport, two markers mounted upon the said support and having tubularextensions on their opposing sides which are adapted to telescope, andmeans for securing the markers in the relative adjusted position,substantially as set forth.

2. In a ruling pen, the combination of a handle, two rotary markersjournaled in the handle upon a support common to each, and a guardarranged adjacent to one of the rotary markers and disposed wholly toone side of a plane passing vertically through the axis or support ofthe markers in the direction of its length, whereby when the-pen isslanted toward the side of the plane farther from the guard both markerswill be in active engagement with the paper, and when the pen is slantedto the side of the plane nearer the guard the marker contiguous to thesaid guard will be lifted from engagement with the said paper,substantially as described for the purpose specified.

3. A ruling pen comprising a fountain handle having a head provided withcheeks, a shaft supported at its ends in the said cheeks, rotary markersmounted upon the said shaft and relatively adjustable to and from eachother to vary the distance apart of the lines to be ruled, and a guardcontiguous to one of the markers and located wholly to one side ofaplane passing vertically through the said shaft in the direction of itslength, whereby when the pen is slanted toward the side of the planefarther from the guard all the said markers will engage with and rulethe paper, and on slanting the pen to the side of the plane nearer theguard, the latter will trail upon the paper and lift the contiguousmarker from operative engagement with the said paper, substantially asset forth.

4;. The herein specified ruling pen, comprising a fountain handle havinga head provided with cheeks, a shaft supported at its ends in the saidcheeks, a single and a double line rotary marker mounted upon the saidshaft and relatively adjustable thereon, means for securing the rotarymarkers in the located position, a distributing pad located between thesaid cheeks, a valve for controlling the supply of ink from the handleto the pad, and a guard forming a prolongation of one of the said cheeksand located wholly to one side of a plane passing vertically through theaxis or shaft in the direction of its length, whereby when the pen isslanted toward the side of the plane farther from the guard both markerswill rule the paper, and when the penis slanted toward the side of theplane nearer the guard only one of the markers will come in contact withand rule the paper, substantially as specified.

In testimony whereofI affix my signature in the presence of twoWitnesses.

LE WIS JOHNSON.
